SNAP

Filed Aug. 14, 1929 Patented June 17, 1930 U ITED srA "res OLNEY THORNLEY, 0F COYLE," OKLAHOMA V SNAP Application filed August 14, 1929. Serial No. 385,874.

My invention relates to spring tongued snaps.

The object device of this class which is new, novel,

practical and of utility; which may be men ufactured in a variety of sizes and shapes; which will comprise an interchangeable tongue and clamping member; which may be quickly and cheaply which will be positive in action; which will be durable; which will be relatively inexpensive in manufacture; which will permit of application use; which will be eiiicient in accomplishing all the purposes for which it is intended.

In spring tongued snaps of present manufacture, in so far as this applicant knows or can ascertain, no means is provided for the quick and cheap replacement of broken springs or spring tongues. A broken spring usually results in a discarding of the snap and all. of its In my device all snaps of a given size are provided with interchangeable spring tongues and clamping means making it possible to quickly and cheaply replace those broken or Worn out thereby saving the loss of the other parts.

With these and other objects in view as will more fully appear, my invention consists in the construction, novel features,and combination of parts hereinafter more fully described, pointed out in the claims hereto appended, and illustrated in theaccompanying one-sheet drawing, of which,

Figure 1 is a perspective view of my device, showing the removable tongue and tongue clamp;

of my inventionis to provide a replacedif broken;

' it is also understood that the drawings are i of the snap to various forms of parts and replacement with Like characters of reference parts in all the figures.

It is understood that various changes in the form, proportion, size, shape, weight and other details of construction, within the scope of my invention may be resorted to without departing from the spirit or broad principle of my invention and without sacrificing any of the advantages thereof; and

to be interpreted as being illustrative and not restrictive.

A practical embodiment of. the invention as illustrated in the drawings comprises: i

A snap hook member 1, having an upwardly and backwardly curved hook end portion 2, culminating in a lip 3. Said member 1 is provided with a shank portion 4-, which in the position as shown in Figure 1, has upon its upper forward side edge portions a pair of curved'upstanding parallel lugs or guides 5. The fist floor 6 of the channel thus formed betweenthe said lugs 5, lies in a plane which, extended toward said lip 3, passes above the under surface of said lip.

Rearward from the said lugs 5, shank 4:, is disposed the clamp -7.

Said clamp 7 is preferably stamped and die out from sheet metal, is formed in an inverted U shape, has a fiat top 8 and two downstanding side portions 9. Said sides 9 are adapted to fit the sides of the said shank 4 and together with said shank 4 are alin'ed- 1y perforated as shownat 10, for the insertion therethrough of a removable holding upon said designate like meansl-l; i V

A flat tongue 13, of spring metal, 1s provided, having an upturned end portion shownas 14.

The said top 8 of the clamp 7 is provided with a slot 12 for seating the said upturned end liWhiCll may be a rectangular perforation as shown in the drawings, or a rectangular notch in the edge of said top 8, if desired.

In usual assembly the said spring 13 is disposed within the channel formed between thesaid lugs 5, its rear end portion clamped V by clamp 7 to theshank 4, with holding means 11, therethrough. The upturned end 14 of the spring 13 is engaged by the said slot 12, the forward end of the spring 13 is disposed under the end portion of the lip 3, which may be recessed as shown at 15, therefor.

The rear end portion of the said shank L is formed as desired, integral with or securely attached to, various forms of attaching members usual to snap hooks, as inclicated at 16 and 17 in Figs. 1 and 6.

In Fig. 5 an embodiment of my device is shown as a double snap, utilizing two spring tongues secured by a single clamp. It will be noted as shown at 18 that one of the springs is inverted, the end li being turned down and disposed within a groove provided therefor in said shank 4.

The case with which the spring tongues of my device may be assembled with ordisassembled from ,thehooks will be obvious.

Obviously, the invention is susceptible of embodimentin forms other than that which is illustrated in the accompanying drawings and described herein, and applicable for uses and purposes other than as detailed, and I therefore consider as my own all such modifications and adaptations and other uses of the form of the device other than as herein described as fairly fall within the scope of my invention.

Having thus described my invention what 1s claimed and desired to be secured by Le ters Patent, is:

1. A snap, as described, embodying a hook having a straight spring, removably clamped to its shank, by an inverted U shaped clamp bolted laterally to said shank and over the shank end of saidspring, said spring ha-vin an upturned end portion engaging a slot in 'aid clamp for preventing lateral and longi- 'tudinal movement of said spring.

2. A snap, as described, embodying a hook having a straight spring adapted to be clamped to the top of its shank, said spring adapted to close the jaw ofv said hook, said spring having a perpendicularly bent end portion, a U shaped clamp having a slot therethrough for receiving said bent end portion of said spring, said clampboltcd to said shank by a bolt passing through its ends and laterally through said shank.

3. A snap, as described, embodying a hook having a shank, a straight spring, a U-shaped clamp for clamping said spring to said shank, said spring. adapted to close the jaw of said hook, a perpendicularly bent end formed on said spring for co-operating with an aperture in said clamp for preventing longitudinal movement of said spring, said clamp adapted to be held on said shank by a lateralbolt.

4:. A snap, as described, embodying a hook having a shank, a straight spring, a U-shaped' clamp for removably clamping said spring to said shank, said spring adapted to contact the point of said hook for closing the space between said point and said shank, a bent end portion formed upon said spring for co-opcrating with an aperture in said clamp for preventing longitudinal movement of said spring.

5. A snap, as described, having in combination, a hook having a shank, a U-shaped clamp, a straight spring attached by said clamp to said shank,- said spring adapted to contact the point of said hook for closing the space between said point and said shank, said shank having a lug upon each of its sides for preventing the transverse movement of saidv spring, a bent end portion formed upon said spring for engaging an opening in the top of said clamp for preventing longitudinal movement of said spring, and a bolt for bolting said clamp to said shank.

6. A snap, as described, having in combination, a hook having a shank, a U-shaped clamp, a straight spring attached by said clamp to said shank, said spring adapted to contact the point of said hook for closing the space between said point and said shank, said shank having a lug upon each of its sides for preventing the transverse movement of said spring, said spring having abent end portion for engaging an opening in the top of said clamp for preventing longitudinal movement of said spring.

7 7. In a. snap, the combination with a hook member having a shank, of a U-shaped clamp, a straight spring attached to said shank by a bolt through said clamp and said shank, said spring adapted to contact the point of said hook for closing the space between said point and said shank, said spring having abent end portion for'engaging an opening in said clamp for preventing longitudinal and transverse movement of said spring.

8. A snap, as described, embodying a hook element, a shank element integral therewith, a tongue element, and a clamping element, said shank having a smooth sloping portion with tongue guide lugs at each side, and having a transverse perforation through its body, said hook element extending longitudinally from one end of said shank element curving thence downward thence upward thence back toward said shank element, said tongue element comprising a flat spring having a perpendicularly bent end portion, said clamping element comprising a U shaped member for fastening together said shank element and said tongue element, and having perforations alined with said transverse perforation for receiving a pin for holding said clamping element on said shank, the bridge of said clamping element having an open space for anchoring said bent end of said clamp, and a bolt laterally disposed through a the ends of said clamp and through said shank for holding said clamp in place.
